Singletrackmind.. how, exactly, are you trimming?

I use hair clippers (like these, incase we're mixing US/UK language )

I attach a No. 1 comb which generally leaves enough hair to lay flat, (no prickles) and just about enough to wax where I don't want any.

If you don't use the comb attachment, it will be very prickly
